INTRODUCTION The lab introduced the relationship between reactants and products‚ and sought to discover which ratio of an acid and base reaction produced the most amount of carbon dioxide gas (CO2) without leaving leftover reactants. 5 varying amounts of bases were added to a constant amount of acid (10 ml) to better understand which ratio was the most efficient. RESULTS Data collected from the lab suggests that the ratio of acid to base that produced the most carbon dioxide gas (CO2) was 1:0.5

Determining the Properties of Different Acids and Bases Yamin Liu November 16th‚ 2017 Chemistry 1021 Section: 427 Benton Smith Discussion of Results The goals of this experiment were to find the identities of four unknown compounds and to first determine the pH. We then were required to run a series of anion and cation tests to determine the composition of the unknown solutions. To get more knowledge about these solutions we ran a series of dilutions to see if

Ph Lab Report Bryon Kim 123013 B(2) Biology Background information/Research PH paper (litmus paper) determines how acidic or how basic a substance is. The paper changes color accordingly to color code on the pH scale. The pH scale starts from 0 to 14. The lower the number the more acidic it is. Zero is the most acidic‚ and 14 is the most basic while 7 is the neutral number for example water. Examples of an acid is lemon juice or multi purpose cleaner. Examples of a basic substance is shampoo or liquid soap

Acid-Base Titration Using a pH Meter Bradley Holloway and Jennifer Parker Period 6 April 16‚ 2013 Introduction: In chemistry‚ the ability to find molarities of acidic and basic solutions is a convenient way to convert between moles of solute and the volumes of their solutions. Through the process of titration‚ the molarity of these acids and bases can be found to a high level of precision. To begin titration‚ one solution is added to a second solution slowly until a certain point

To test the effect of adding an acid or base to a buffer solution. SAFETY CONCERNS: Always wear safety goggles. Wash with soap and water if skin contacts acids or bases. ACIDS: An Acid is a substance that when dissolved in water will produce hydrogen ions‚ H+‚ in the solution. An acid that does not contain carbon is called an inorganic

Decreased pH in the blood is generally known as acidosis. The body cells continuously respire and release carbon dioxide. The lungs may fail to efficiently expel the CO2. This condition is known as alveolar
